  • Web attack uses structural, logical and coding error or web application rather than vulnerability to Web server itself. According to the Open Web Application Security Project (OWASP) published about ten types of the web application vulnerability to show the causes of hacking, the risk of hacking and the severity of damage are well known. The detection ability and response is important to deal with web hacking. Filtering methods like pattern matching and code modification are used for defense but these methods can not detect new types of attacks. Also though the security unit product like IDS or web application firewall can be used, these require a lot of money and efforts to operate and maintain, and security unit product is likely to generate false positive detection. In this research profiling method that attracts the structure of web application and the attributes of input parameters such as types and length is used, and by installing structural database of web application in advance it is possible that the lack of the validation of user input value check and the verification and attack detection is solved through using profiling identifier of database against illegal request. Integral security management system has been used in most institutes. Therefore even if additional unit security product is not applied, attacks against the web application will be able to be detected by showing the model, which the security monitoring log gathering agent of the integral security management system and the function of the detection of web application attack are combined.

  • The purpose of this study was to develop and apply a Korean language education program based on multiple intelligences in a bid to foster the multiple intelligences, self-efficacy and achievement motivation of elementary schoolers in regular language arts class. It's basically meant to create the educational conditions for every child to exert his or her abilities. Two research questions were posed: 1. What should be the objectives, content and teaching-learning methods of a Korean language education program based on multiple intelligences? 2. What effect does a Korean education program based on multiple intelligences have on children's multiple intelligences, self-efficacy and achievement motivation? The subjects in this study were 58 Students in two different third-grade classes in M elementary school in the city of Daejeon. A Korean language education program based on multiple intelligences was implemented during a 4month period of time, and an inclusive approach of multiple intelligences and cooperative learning were applied. The major findings of the study were as follows: First, in order to develop a Korean education program based on multiple intelligences, the kinds of themes that could cover multiple intelligences in an inclusive way were selected in consideration of the learning objectives of the major units of a third-grade language arts textbook(second semester) of the 7th national elementary language arts curriculum. And then an inclusive Korean education program was prepared, which consisted of four stages: problem awareness, problem-solving planning, problem solving, and reflection/application/development. Second, the Korean education program based on multiple intelligences had a positive effect on the children's multiple intelligences, self-efficacy and achievement motivation and suggested some of new directions for school education that typically stressed linguistic and logical-mathematical intelligences only.

  • Nonlinear Invariant Attack is an attack that should be considered when constructing lightweight block ciphers with relatively simple key schedule. A shortcut to prove a block cipher's resistance against nonlinear invariant attack is checking the smallest dimension of linear layer-invariant linear subspace which contains all known differences between round keys is equal to the block size. In this paper, we presents the following results. We identify the structure and number of optimal bit-permutations which require only one known difference between round keys for a designer to show that the corresponding block cipher is resistant against nonlinear invariant attack. Moreover, we show that PRESENT-like block ciphers need at least two known differences between round keys by checking all PRESENT-like bit-permutations. Additionally, we verify that the variants of PRESENT-like bit-permutations requiring the only two known differences between round keys do not conflict with the resistance against differential attack by comparing the best differential trails. Finally, through the distribution of the invariant factors of all bit-permutations that maintain BOGI logic with GIFT S-box, GIFT-variant block ciphers require at least 8 known differences between round keys for the resistance.

  • This article will divide agricultural change process in Yanbian area into the period of japan rule, socialism and later time of the reform and open policy and so on. It will analyze the changes of Yanbian agriculture in every period influenced by external environment influence. The conclusions are as follow: first, under the influence of the japan rule, the policy about Korean Minority immigrants in japan and the original work agriculture and the group tribe construction, Yanbian fanning was controlled by the Japanese. Therefore, Yanbian's agriculture became the tool to satisfy the war and plunder the resource for Japanese. It shows the obviously peripheral characteristics. Second, in socialism time, Yanbian's agriculture was influenced by the rural communalization. The fanning completely belongs to the country, the agricultural production is influenced by the idea of "grain as the key link" which it only pays attention to take the cultivation industry and the production of grain in the interior of cultivation industry. Therefore, it has not been able fully to use the rich natural resource. Third, after reform and open policy, the countrysides were implemented family contract responsibility system, the farmer can rent the land for a long time, and the enthusiasm of agricultural production was improved. Moreover, due to the social market economy-system, the farmer carried on the agricultural production activities according to the market's demands and various departments of the agriculture obtained the coordinate development.

  • Within any income approach, a discount rate is used to convert some projected free cash flow to its presented value. In case of valuing companies, the most frequently used discount rate is the weighted average cost of capital(WACC) at the aggregate level. But technology valuation is different to discounting aggregate corporate cash flow since it is concerned about individual Intellectual property. Therefore, blindly applying standard discount rate such as WACC in technology valuation is unlikely to lead to the right result. The primary focus of this paper is to establish the structure of discount rate for technology valuation and to suggest the method of estimation. To determine an appropriate discount rate for technology valuation, the level of technology risk, market risk and competitive risk should be included in the structure of discount rate. This paper suggests the build-up model which consists of three components as a expansion of the CAPM. It includes (1) a risk-free rate of return, (2) general market risk premium and beta and (3) intellectual property risk premium related to technology risk and specific target market risk. However, there is no specific check list for examining the intellectual property risk until now and no specific method for quantifying its risk into risk premium. This paper developed the 10 element to determine the level of the intellectual property risk and applied estimation function such as linear function, natural log function and exponential function to transform the level of risk into risk premium. The limitation of this paper is that the range of intellectual property risk premium is inferred based on the information of foreign and domestic valuation agency. Finally, this paper explored the development of an intellectual property discount rate for technology valuation and presented the method in order to quantify the intellectual property risk premium.

  • This study aimed to investigate data management practices of university researchers in Korea, as well as their experiences and perceptions of data sharing and reuse. For this purpose, it performed semi-structured interviews of 13 researchers who agreed to participate in interviews followed by a survey conducted prior to this study. The interview participants created or collected research data with various types and formats, and only a few conducted data documentation while they recognized its significance. The majority of participants perceived the period that data would be useful as the period that data can be employed for publications. However, most participants wanted to preserve data beyond the period that data would be considered useful and it indicates they have no small need for data storage and preservation. Participants usually shared data with those whom they have known, such as a personal research group or a research team. While some completely agree with the principle that publicly-funded data should be open to the public, others partially agreed or disagreed with it. Most participants were concerned about being scooped, plagiarism, and maintaining the first right to publish and incentives to mitigate the concerns would be necessary.

  • 현재 공적연금제도의 하나인 사학연금은 일반 민간 기업에서 퇴직시에 지급하는 퇴직금과 유사한 성격의 '퇴직수당' 급여를 지급하고 있다. 사립학교연금법에서 지급하고 있는 퇴직수당제도는 학교법인인 사용자가 지급할 의무가 있는 급여에 해당한다. 그러나 사립학교의 열악한 재정으로 인하여 학교법인이 지급하지 아니하고 이를 국가와 공단 및 대학의 일부가 이를 분담하여 지급하고 있다. 사학연금공단에서는 매년 236억원을 연금기금에서 지급하였으며, 동 금액은 기부금으로 손금산입되어 왔다. 그러나, 최근 들어 기부금의 손금 인정비율이 50%로 축소되어 실제 법인세를 납부하고 있다. 본 연구에서는 이러한 퇴직수당 공단부담금을 공단에서 부담하는 것이 타당한지 여부와 기부금으로 처리되는 것에 대한 타당성 여부 등에 대하여 세무회계적인 접근을 통해 법인세제개선을 위한 법 개정의 타당성을 살펴보고자 하였다. 본 연구는 퇴직수당 공단부담금이 기금회계에서 지급되어 기부금으로 보고 있는 기존의 예규에 대한 해석을 새롭게 하고 사학연금기금의 세무회계상 개선방안을 도출하고자 하였다. 퇴직수당의 급여지급은 엄밀하게 살펴보면 기금회계의 대상이 아니라 연금제도의 고유사업인 연금회계의 대상으로 보는 것이 타당하다. 이와 같은 현행 공단의 회계처리 및 기금회계 과세대상의 문제점을 인지하고 이를 면밀히 분석해보고자 한다. 본 연구는 사학연금기금의 법인세 부담으로 인한 연금재정악화를 사전에 방지할 뿐만 아니라 사학연금기금에 대한 안정화를 도모하고자 하는 방안 연구의 일환으로 법적 개선안 도출을 목적으로 하고 있다. 공단은 사립학교 법인을 대신하여 공단에서 대신 지급하면서도 이에 대해 기부금으로 보는 규정으로 인해 법인세를 납부하고 있어 부담금을 대신하여 납부하면서 법인세도 부담하고 있는 이중부담을 안고 있는 것이다. 본 연구에서는 이와 같은 사항을 토대로 다음과 같이 개선방안을 제시하고자 한다. 우선, 공단내부회계규정의 수정을 통해 퇴직수당의 연금회계 적용을 주장하고자 한다. 퇴직수당제도는 연금급여와 관련된 것으로 비과세대상의 고유목적사업 회계에 해당됨에도 불구하고 퇴직수당을 기금회계에서 기부금으로 처리하는 것은 법 논리상 타당하지 않다고 본다. 둘째, 학교법인을 대신하여 기금에서 대신 지급하였다는 것은 연금제도를 유지하기 위해서 연금법상에서 강제로 부과된 부담금으로 이를 필요경비로도 보아야 한다. 셋째, 학교경영기관이 마땅히 부담하여야 할 부담금임에도 불구하고 사학연금기금에서 부득이하게 지급하고 있음을 감안하여 퇴직수당부담금은 현행의 법인세법상 기부금 한도초과 대상에서 제외하는 특례규정을 신설하는 것이다. 본 연구는 최근 법인세가 과세되고 있는 사학연금기금의 과세 문제점을 살펴보고 이에 대한 개선방안을 제시하였다는 점에서 기존 연금제도의 틀 안에서 퇴직수당제도의 법적 부담을 검토한 연구와는 달리 법인세법상의 세무적 검토를 하였다는 점에서 의의가 있다고 할 수 있다.

  • Nog-Moon Yim Seong-Joo(녹문 임성주) is a philosopher of late Choseon Dynasty of the 18th Century. He concluded that the debates between the school of Ho and that of Rack originated from the seclusion of Li(理) and Ki(氣), and theorized the new Li and Ki theory according to his own perspective. The prime point of Nog-Moon's Philosophy is said to be Li-Ki dongshil(理氣同實), Mind and Nature ilchi(心性一致) ; he proves his prime potints based on his pure and clean Ki substance. Thus Li-Ki is reduced to monism from dualism, and Mind-Nature(心 性) is reduced to mind. Since the basis of the existence of Mind is Ki(氣), Nog-moon's theory of Substance is concluded to be Ki-monism. Nog-Moon presents his great philosophy of Ki monism suggested by Jeong Myeong-Do's monistic methodology; he explains the universality of Substance and the diversity of Phenomenon with the logical structure of ilwonbunsu(一原分殊). The characteristics of Nog-Moon's philosophy is that ilwon(一原) and bunsu(分殊) are bonnyeon(本然) identical, which means Substance and Function(體用) are identical, or bonmalilchi(本末一致). It means Mind and Nature are bonnyeon(本然) identical, Ki and Mind and Nature are identical. With the expression of seongrihak (性理學) Gijil(氣質) is not different from bonnyeon(本然). Therefore 1 define the philosophy of Nog-Moon had been built on the context of a sage.

  • 'Gyeokmulchiji' (格物致知), coming to knowledge based on the investigation of things) is a starting point for any study and politics of Confucianism. Much emphasis was placed on the conception of 'Gyeokchi' as a root of every learning and adminstration in the early Joseon period. As Confucianism established itself as a salient value system of the government, a mighty change and paradigm shift happened in its governmental system which had depended upon Buddhism up to that time. Thus, Confucian statecraft also stood out. Daehakyeonui (大學衍義) was preached as a model of regal learning and politics in the governmental agon, and its conceptual starting point was 'Gyeokchi.' The various interpretations and arguments about this concept shows the process in which Zhu Xi NeoConfucianism was deepened into Neo-Confucianism of Joseon's own. This conception reached the essence of 'Li' beyond the problem of cognitive subject and object, and provided a watershed which divided Giho (畿湖) and Yeongnam (嶺南) schools. Confucian method of study, which incorporates knowledge and practice, has great implications for our times when there are many voices of concern over humanities. The enhancement of universities and humanities is much needed to adjust the direction and pace of scientific technology, which is now entirely left with the logic of market. Accordingly, it is quite urgent for us to examine our object of learning again, which should integrate 'Sugi' (修己, cultivating oneself) with 'Chi-in' (治人, governing others), and knowledge with practice.

  • Both An, Joonggeun and Park, Youngcheol lived in similar innovative time period from the enlightenment times through the Japanese colonial era. Even though they had the same resolution to pour their energy on national sovereignty and oriental peace, their opinions and activities were contrary. While An aimed the gun at the heart of Japanese imperialism with the belief that Japanses empire hindered Korea's independence and the Oriental Peace, Park willingly joined the heart of the imperialism with the belief that Japan could enhance Korean civilization and the Oriental peace. They had commonly developed their visions about oriental peace on the basis of the theory of social evolution focusing on the survival of the fittest and the weak-to-the-wall kind of society that had been prevalent since 19th century. Furthermore, their logics were based on racism combined with the social evolution theory. Although the two men lived in the same era, their spirit of the times were quite different. An considered that the Japanese extortion of Korean sovereignty caused the corruption of peace of the East. On the other hand, Park believed that peaceful age came by way of the Greater East Asia Co-Prosperity constructed by the union of Korea and Japan. Especially Park put higher value on Japanese modern civilization than Korean sovereignty and also insisted Korea should take Japanese case as its model.
